I don't know what you mean by Luthor, but the pig is Wonder Woman. There's an episode where Circe turns her into a pig and Batman recruits a small group to track her down. It sounds ridiculous but it's actually an awesome episode.

The pig is Wonder Woman transformed by Circe and an episode was spent trying to track her down and get Circe to change her back. Batman saved the day by singing a rather nice croon at dinner theatre if I recall correctly.

What do you want to know about Luthor? The pic isn't loading at work due to some idiotic blockers that are in place for no reason ...

As for the Batman Animated figures...well it does say on the bottom of the "poster" that this list includes figures from Batman, JL and JLU. I dunno about you guys/gals but I display more than a few BTAS figures with my JLU anywho.

I think its more b/c Mattel re-released these at big lots and places like that

The only reason some of those figures are on there is because the creator considered them part of the line. Even the ones that did come out under JLU like Penguin, Batgirl and Nightwing, were on the poster before that point.
